我们在使用红外线分析仪中体会到,除根据工艺特点合理选择安装方式和精心维护外,对光路平衡和相位进行正确调整,是保证仪表灵、准、稳的一个重要环节。仪表在使用中存在的漂移较大,量程和线性不好,均与此有关,因此,必须在实践中了解它们的原理,方能掌握规律和进行熟练的调整。 We use the infrared analyzer experience, in addition to the process according to the characteristics of a reasonable choice of installation and careful maintenance, the optical path balance and phase correctly adjusted, is to ensure instrument spirit, accurate, stable an important part. Instrument in use there is a large drift, range and linearity are not good, are related to this, we must understand their principles in practice, in order to master the rules and make a skilled adjustment.
